Your Kua number is a dynamic feng shui practice for determining your auspicious and inauspicious directions with simple numerology. The formula, called the Eight Mansions Kua Formula, is very simple and easy to follow. The calculation is broken down into two easy steps, using your birth year and gender. You're just minutes away from discovering your personal kua number.

Kua Number Explained

While feng shui practices and elements improve the flow of chi in your home, your personal kua number helps you thrive in your surroundings and improve your personal energy and luck. Once you know your kua number and your lucky and unlucky directions, you will be unlocking the powerful energies of positive chi and learning how to mitigate inauspicious energy in your personal environment. Also called your personal feng shui number, you can also use your number to enhance your kua number personality traits.

Calculate My Kua Number

To calculate your feng shui kua number, you will need the following information:

  • Birth year
  • Gender
  • Optional calculator, only if needed.

Step 1: Add Last Two Digits of Your Birth Year

Add the last two digits of your birth year together.

Example:

1981 = 8 + 1 = 9

Some dates may give you a double digit answer. Simply add these together until you arrive at a single digit. This is called the Kua Factor.

Example:

1985 = 8 + 5 = 13

1 + 3 = 4

Step 2: Add or Subtract Based on Gender

Next, you will either add or subtract numbers from your single digit birth year result depending on your gender. These numbers depend on whether you were born before or after 2000.

While most personal number calculations are based on gender at birth, you can also choose to calculate the Step 2 math based on your gender identity.

If you're a female and were born before the year 2000, you will need to add 5 to your single digit year result. This will give you your Kua Number.

Example of a female birth year 1981 added down to 9 in Step 1 looks like this for the second step:

9 + 5 = 14

For two-digit results, you'll need to add them again to reach the appropriate number.

1 + 4 = 5 (Kua number)

If you're a female with a birth year of 1985 added down to 4 in the first step, the second step looks like this:

4 + 5 = 9 (Kua number)

Kua Number Calculator for Females Born After 2000

If you're a female born after 2000, download and print the calculation worksheet below.

Alternatively, you can add 6 to your year result (single digit).

Example of a female birth year 2005 added down to 5 in the first step results in the following:

5 + 6 = 11

Again, if the result is two digits, add them together to reach a single digit.

1 + 1 = 2 (Kua number)

Alternatively, you can subtract your single digit year result from 10. This will give your Kua number.

Example of a male birth year 1981 added down to 9 looks like this:

10 - 9 = 1 (Kua number)

For a male birth year 1985 added down to 4 looks like this:

10 - 4 = 6 (Kua number)

If you're a male born after the year 2000, download and use the worksheet below.

Alternatively, you can subtract your single digit year result from 9. This will give your Kua number.

9 - 5 = 4 (Kua number)
